Marl is a useful substitute for the hard limestones for some pur- 
poses and is rather extensively developed in the central and western 
parts of the State. It is found particularly in swampy tracts and 
old lake basins associated with clay and peat. In the Cowaselon 
swamp near Canastota the marl underlies several thousand acres 
and is said to be 30 feet thick. The Montezuma marshes in Cayuga 
and Seneca counties contain a large deposit which at Montezuma 
is 14 feet thick. In Steuben county the marls at Arkport and Dans- 
ville have been employed for lime-making. Until recently marls 
have been used extensively for portland cement and plants -were 
operated at one time in the marl beds near Warner and Jordan, 
Onondaga county; at Montezuma, Cayuga county; Wayland, Steu- 
ben county ; and Caledonia, Livingston county. Their principal use 
at present is for agricultural and chemical purposes. 
Production of limestone. The limestone quarried for various 
uses constitutes more than one-half the total value of the quarry 
products of the State. The proportion would be even more in 
favor of limestone if the stone consumed in portland cement manu- 
facture was reckoned in the total, but that is excluded in order to 
avoid duplication of the statistics. 
The reports submitted by the quarry companies indicate a very 
large increase in the output for 1912, the total value of which 
amounted to $3,510,445 against a value of $3,174,161 in 1911. The 
advance raised the figures above those for any previous year; the 
next highest total was $3,300,383 in 1909. As in other branches of 
the industry, no account has been made of the stone quarried by 
contractors in connection with road improvement work, for which 
it is impossible to secure reliable data.
